Hot rolled steel section B-2 Wear Resistant Material
Hot rolled steel section B-2
Rolling steel is a type of ordinary hot-rolled steel that has undergone strong drawing and exceeded the strain hardening stage. It has high strength, but poor toughness, weldability, and is relatively hard and brittle. Hot rolling is processed at high temperatures. Hot rolling refers to the heating of materials during or before the rolling process. Generally, rolling is carried out after heating to above the recrystallization temperature.
